Description

Technical field

The present invention relates to a power plant, and more particularly to a wind power plant that utilizes wind to generate energy. Background technique

In general, the energy used in industry is mostly non-renewable energy such as petroleum and coal. Therefore, as industries in various countries develop gradually, the demand for energy increases, resulting in a gradual shortage of stocks and a global energy crisis. In addition, the waste generated by the use of these non-renewable energy sources has gradually caused problems in global climate change. In recent years, with the strengthening of environmental awareness, countries have successively advocated the concept of energy conservation and emission reduction, hoping to delay or even improve the speed of human destruction of the environment and the consumption of the earth's resources. Therefore, reduce the consumption of non-renewable energy and find new alternative energy sources. And the development of renewable energy has become the focus of recent developments in some developed countries.

Renewable energy includes solar energy, wind power and tides. Among them, in the case of wind power generation, wind power is mainly used to drive a wind turbine to generate the required power. The common wind turbines are roughly divided into vertical shafts. And the horizontal axis type; vertical axis type wind turbine, the root axis of the blade is perpendicular to the ground, and the horizontal axis type wind turbine has the root axis of the blade being horizontal with the ground.

At present, the existing vertical axis wind power generator 9 (shown in FIG. 1) includes a rotating shaft 91. The rotating shaft 91 is provided with a plurality of curved blades 92, and one end edge of the plurality of curved blades 92 The rotating shaft 91 is fixed to the rotating shaft 91 in an equiangular radial direction in the radial direction of the rotating shaft 91. One end of the rotating shaft 91 is connected to a power generating device 94 via a coupling 93. In this way, when the above several blades When the wind is blown by 92, the rotating shaft 91 can be rotated to drive the power generating device 94 to generate electric power, and the generated electric quantity is proportional to the rotational speed of the rotating shaft 91. However, the vertical shaft wind turbine 9 has the following disadvantages:

First, the wind flow cannot be adjusted: Since the wind is a natural phenomenon, the size of the wind depends on the natural conditions and cannot be controlled by humans. The stronger the wind, the higher the rotational speed of the rotating shaft 91, but each set of power generating devices 94 has an upper limit of operation. In order to avoid strong winds (such as gusts with wind speeds greater than 75 meters per second during typhoon), the rotating shaft 91 rotates at a high speed to cause the power generating device to be overloaded and damaged, and the existing vertical shaft wind turbine 9 does not have the ability to adjust the intake air flow. Structure, therefore, a brake system must be set up to activate the brakes to protect the power generation device 94 when the wind is too large, and even stop to avoid overloading the unit; however, setting the brake system increases the complexity of the vertical shaft wind turbine 9 structure, making the manufacture The cost is increased, and the downtime causes the power generation operation to stop and cause losses. In addition, since the blades 92 are required to withstand winds of different directions and strengths, they are required to be made of high-strength and fatigue-resistant materials, which are greatly limited in the selection of materials, and also cause the manufacturing cost of the blades 92. High.

Second, the wind angle cannot be adjusted: Since the wind blown on the blade 92 comes from an indefinite direction, and the existing vertical shaft wind turbine 9 does not have a structure capable of adjusting the inlet angle, the different inlet angles are The wind may provide rotational power in the opposite direction. Later winds may form the resistance of the previous wind to push the blades 92 to rotate, resulting in high starting wind speed and low utilization of wind energy. Therefore, for the existing vertical shaft wind power generator 9, The utilization of wind energy during breeze is particularly poor, and it is even impossible to act.

3. It is impossible to set up in series: each of the existing vertical axis wind turbines 9 is provided with a power generating device 94, and each of the vertical axis wind power generators 9 cannot be connected in series because there is no connection structure, so if a large power generation is desired When the device 94 is used to increase the amount of power generation, the only way is to enlarge the blade 92. However, the large blade 92 has a certain technical difficulty in manufacturing, so that a certain degree of difficulty is achieved. The total power generation, the industry can only replace a large vertical shaft wind turbine 9 with several small vertical shaft wind turbines 9, which increases the cost and greatly limits the promotion of wind power generation. Summary of the invention
